02-10-1988 - Workshop o o CITY COUNCIL OF EDGEWATER WORKSHOP FEBRUARY 10, 1988 MINUTES Mayor Baugh called the Workshop to order at 6:01 P.M. in the Community Center. He stated the purpose was for the presentation by Dyer, Riddle, Mills & Precourt, Inc. of the technical aspects of the City-wide water distribution system improve- ments related to the Capital Improvement Program. He suggested members of the audience move forward to have ample visibility of the slide screen presentation. ROLL CALL Mayor Earl Baugh Councilman Louis Rotundo Councilman Russell Prater Councilman Neil Asting Present Present Present Present Councilman David Mitchum City Attorney Jose' Alvarez City Clerk Connie Martinez Chief Lawrence Schumaker Present Absent Present Present Also present from Dyer, Riddle, Mills & Precourt, Inc. were: Mr. Ron Ferland, Mr. Harold Nantz, and Mr. Tim Hochuli. Ron Ferland, Project Manager, reviewed previous presentations briefly. He stated they're going to talk about pipe line distribution and they're developing a distri- bution system model that will simulate the City's system. He pointed out that the figures are preliminary and will be high with the intent of whittling them down to a more reasonable cost. Mr. Ferland stated the hydrant analysis was set up with a computer model and they assembled data by going through the water records, based on consumption over the past three years, and looked at all the water maps and plans drawn for the water system. He said they laid out the pipe and node system. He said they assigned water demands by taking actual flow through the metal readings and got a total 30 day month and defined a peaking factor of the time of day when they're using the most amount of water. Mr. Ferland stated the computer told them pressure in the south end of Florida Shores based on flow conditions. He said if they had a fire on the east side of U.S.l they determined that pressure, and they conducted field tests to simulate flow and took pressure readings around the distribution service area. He said they're at a calibrated model that efficiently and accurately detects any conditions that would be put on the system, and when they put a new subdivision on the system, they'll be able to tell the affect on the distribution system. He added that they used the model to effectively determine what the CIP needs are and how to improve it. He showed on a chart the conditions and deficiencies where additional pipe needs to be, or upsized. He pointed out that Florida Shores is loaded with 2" line and they need to put 6" lines for needed improvements. Mr. Ferland noted they used the 1987 actual flow conditions that occurred and then looked at 1995 with anticipated growth. He added that average daily flow over the l2-month period is 1.07 in 1987 and 2.13 MGD in 1995. He said the maximum daily flow with the worst 30-day period was 1.76 MGD in 1987 and 3.49 MGD in 1995. He reviewed other figures for 1987 compared to anticipated 1995. Mr. Ferland stated that adding a 12" main extension to the Florida Shores ele- vated tank will be a tremendous benefit to Florida Shores to maintain pressure. He showed on the chart the projected City-wide fire protection service to pro- vide fire hydrants in residential neighborhoods to be in conformity with standards. He noted they should be 800 feet apart and -the fire trucks would be no further than 500 feet from any fire hydrant. Mr. Ferland stated that on run #4 they added the western water treatment plant with 20" water distribution main running down 442. He said they went to Air Park Road and then looped around the Florida Shores neighborhood. He reviewed run #5. Mr. Ferland stated that deficiencies for water distribution would be below 40 PPSI the normal consumptive use flow and above 20PPSI for fire flow and maximum data. He said 20 lbs. is to be maintained by law and if it goes below that, they have to flush it and do bacterial monitoring. o o Mr. Ferland reviewed other runs that were done regarding low pressure in Florida Shores, fire protection, fire hydrants in Florida Shores and some at Thomas Street and north of City Hall area east of u.S. 1. Mr. Ferland noted at that area south of Florida Shores at about 1997 or 2000, the 12" line that comes down 442 will not be able to meet the maximum daily flow needs for Florida Shores. He showed that they didn't have adequate fire protection south of Edgewater. Mr. Ferland stated that based on deficiencies delineated to date, the construction cost associated with water system improvements with the first cut before fine tuning is 6,950 linear feet of 12" PVC needed and this 12" pipe line was recently approved running down Mango Tree to the elevated tank in Florida Shores. He added that's a projected cost of $145,000 installed, and not just the materials cost. Mr. Ferland stated that improvements necessary to provide residential fire flow is 80,000 linear feet of 6" PVC at $12 a foot for a total of $960,000. He noted that 78,000 feet is in the Florida Shores neighborhood and 2,000 feet of 6" extensions is off Thomas Street and north of City Hall and east of u.S. l. He said there are 400 fire hydrants at a cost of $420,000, 358 in Florida Shores and remaining 42 in areas indicated. He pointed out the total fire protection cost is 1.38 million dollars. Mr. Ferland stated that improvements necessary to provide inudstiral fire pro- tection flow in the existing industrial parks in the City limits is 1,600 foot of 8" pipe line for $27,000, 2,600 linear feet at $18 per foot, and 25 hydrants, for a total of $100,050. Mr. Ferland stated the 12" extension going down Air Park Road up Roberts Road and back through Florida shores and water conduit to serve future growth south of the City limits is 18,000 linear feet of 12" pipe at $394,800, plus 10 fire hydrants at $405,300. Mr. Ferland stated that the total cost of all improvements reviewed at this meeting is $2,031.300. Mr. Ferland stated they put the improvements in phases, the same as wastewater construction. He said phase I would be one block north of 442, Mango Tree Drive, at an estimated cost of $165,500. He said phase 2 has a breaking point at 30th Street with a cost of $585,650. He said phase 3 is $562,650. He displayed the areas on the chart for all to see. Mr. Ferland pointed out the repaving costs were in the wastewater costs and they can divide that to pay a proportionate share. Mr. Ferland stated he can come back with a follow up or leave it at this and give a final report, as the context and concept will not change much, but the costs will. Mayor Baugh asked for Council comments and there were none. Norman Billups, 1860 Pine Tree, asked for comments regarding issuance of certifi- cates of occupancy to homes regarding the flushing out of lines before the certifi- cate is issued by the City or builder in order to guarantee freedom of bacteria when the owner first moves in. Mr.Ferland replied that he would think the builder would have flushed out the lines prior to occupancy because if he doesn't and the lines are clogged, he'll have to unclog the line under the one-year warranty. He added the certificate of occupancy issued or not isn't the concern. Mr. Billups stated he thinks the City would be responsible and the Building Inspector should protect the people from undue exposure to bacteria and other contaminants. Mayor Baugh asked Dennis Fischer, Building Official/Code Enforce- ment Officer, if he checks that, and Mr. Fischer replied that it would tie into the water mains and the water department has that responsibility. Mayor Baugh asked Terry Wadsworth, Utilities Superintendent, about it, and Mr. Wadsworth replied not specifically tests on the house, but they could take a chlorine residual after flushing the line to the house, and they do insure that the City lines and water carry a chlorine residual and are free from bacteria. He added they could incorporate that if Council wishes, but it's not being done now. -2- Council Workshop Minutes February 10, 1988 J . . o o , I Frank Roe, 2732 Juniper Drive, asked if the Florida Shores water tank is in a good enough condition to keep it in service, and how long it will be. Mr. Ferland replied that water tanks can last a long time and it's probably about 25 years old now. Mr. Terry Wadsworth, Utilities Superintendent, stated the name plate is 1965. Mr. Ferland added that he sees no problem with that and as Chairman of the Waterworks American Landmark Committee he has given landmark awards to tanks over 80 years old and they have to inspect it regularly and provide a thorough coating to preclude any rust from forming. Liz'Taylor, 2115 Travelers Palm, asked if the property's built on swamp land. Mayor Baugh replied that if it is, he doesn't know Mayor Baugh thanked Mr. Ferland for the presentation, and requested a motion to adjourn the Workshop. Councilman Prater so moved. Councilman Mitchum seconded the motion. Workshop was adjourned at 6:35 P.M. Minutes submitted by: Lura Sue Koser ATTEST: COUN7~7~ COUNCILMAN - ZONE FOUR Acting) Approved this 7 day of ~~ ,198tf'.
